A Timeless Treasure: Grandma’s Secret Recipe
The origins of truly great recipes often lie in cherished family traditions, passed down through generations. This particular Chicken and Broccoli Casserole holds a special place in my heart, a delightful gift from my husband’s wonderful grandma. It arrived in response to an email I sent out, sparking what I affectionately call “this wild ride” – a journey into sharing more beloved family recipes, a story you can explore further on my about page.
I first received this recipe at the perfect time, with a generous amount of leftover turkey breast from a batch of homemade turkey and egg noodles. It immediately struck me as the ideal way to transform those leftovers into something entirely new and exciting. While leftover turkey is fantastic, this recipe is incredibly versatile. You can just as easily use leftover roast chicken, cook up some fresh chicken breasts specifically for the dish, or even grab a convenient rotisserie chicken from the store for a truly effortless start.

One of the many beauties of this casserole is its make-ahead potential. Knowing I had a busy day ahead, I prepared the entire casserole the night before, stopping just shy of adding the final layer of cheese. It then nestled comfortably in the refrigerator overnight. The next evening, arriving home after a long day, all I had to do was pull it out, preheat the oven, and sprinkle on the cheese. I added a few extra minutes to the baking time to account for the casserole starting cold, and the result was pure perfection.
Every single time this dish makes an appearance, it’s met with enthusiastic approval. That first taste, years ago, solidified its spot in my recipe rotation. Now, it’s my go-to whenever I have leftover poultry, making an appearance a few times a year. My family, bless their hearts, seems to have a selective memory when it comes to this dish, reacting with fresh excitement as if it’s their first encounter, every single time. And honestly, I don’t mind one bit, because their delight is infectious!
If you’re seeking a quick, satisfying, and utterly delicious way to reinvent leftovers, look no further. This recipe is your answer. And don’t let a lack of pre-cooked chicken deter you; it’s absolutely worth cooking up some fresh chicken breasts or thighs to enjoy this incredible casserole from scratch. Grandma truly hit it out of the park with this one. I’m definitely going to inquire if she has any more culinary gems hidden in her recipe box!

Can I use fresh broccoli in this recipe?
Absolutely! If you prefer the crisp texture and vibrant flavor of fresh broccoli over frozen florets, you can certainly make that substitution. However, fresh broccoli generally takes a little longer to cook through, especially when baked in a casserole. To ensure it reaches that perfect tender-crisp texture without becoming mushy or staying too firm, I recommend partially cooking it before adding it to the casserole mixture.
A quick steam for about 3-5 minutes until it’s bright green and slightly tender, or a minute or two in the microwave, will do the trick. This pre-cooking step guarantees that your broccoli will be perfectly cooked by the time the casserole finishes baking, contributing beautifully to the overall texture and taste of the dish.


Assemble It Ahead Of Time for Ultimate Convenience
Life can be hectic, and having a delicious, homemade meal ready to pop in the oven is a game-changer. This Chicken and Broccoli Casserole is an excellent candidate for advance preparation. To get ahead, simply follow the recipe instructions all the way up until it’s time to put the dish in the oven. Once assembled in your casserole dish, cover it tightly with aluminum foil to protect its freshness and refrigerate.
This pre-assembled casserole can be stored in the refrigerator for up to two days, making it perfect for meal planning. When you’re ready to bake, take the casserole out of the refrigerator while your oven preheats. This allows it to come closer to room temperature, which helps ensure even cooking. Bake the covered casserole for an initial 10 minutes, then remove the foil and continue baking for another 20 minutes, or until the creamy sauce is bubbling around the edges and the cheese on top is beautifully melted and golden. This method ensures a hot, comforting meal with minimal effort when you need it most.

Ingredients
- 8 ounces egg noodles
- 3 Tablespoons butter
- 1 onion chopped
- ¼ cup all purpose flour
- 1½ cups chicken broth
- ¾ cup milk
- 4 cups shredded chicken or turkey!
- 12 ounce package frozen broccoli thawed
- 1 cup shredded cheddar cheese
- 1 cup shredded provolone cheese
Instructions
-
Preheat your oven to 400°F (200°C) to ensure it’s ready for baking.
-
Cook 8 ounces of egg noodles according to the package directions until they are al dente. This means they should be firm to the bite, as they will continue to cook slightly in the casserole. Drain the noodles thoroughly and spread them evenly in a greased 9×13-inch baking pan.
-
In a saucepan over medium heat, melt 3 tablespoons of butter. Add 1 chopped onion to the melted butter and sauté until the onion softens and becomes translucent, about 5-7 minutes. This step adds a crucial layer of flavor to the sauce.
-
Sprinkle ¼ cup of all-purpose flour over the softened onions and butter. Cook for about one minute, stirring constantly. This creates a roux, which will be the base for your creamy sauce.
-
Gradually pour in 1½ cups of chicken broth, whisking continuously to prevent lumps and ensure the flour is fully incorporated. Once smooth, add ¾ cup of milk and continue to cook over medium heat, stirring frequently, until the sauce thickens to your desired consistency. It should be rich and creamy.
-
Evenly distribute the 4 cups of shredded cooked chicken (or turkey) and the 12-ounce package of thawed frozen broccoli over the cooked noodles in the baking pan. Pour the freshly made creamy sauce over the chicken, broccoli, and noodles, ensuring everything is well coated.
-
In a small bowl, combine 1 cup of shredded cheddar cheese and 1 cup of shredded provolone cheese. Generously sprinkle this cheese mixture over the top of the casserole, creating a delicious crust.
-
Bake for 20 minutes, or until the sauce is bubbly around the edges and the cheese topping is beautifully melted and golden brown. Let it rest for a few minutes before serving to allow the flavors to meld and the sauce to set slightly.
